如何在 Django 中对文件上传进行单元测试 [英] how to unit test file upload in django

问题描述

在我的 django 应用程序中，我有一个完成文件上传的视图.核心片段是这样的

In my django app, I have a view which accomplishes file upload.The core snippet is like this

...
if  (request.method == 'POST'):
    if request.FILES.has_key('file'):
        file = request.FILES['file']
        with open(settings.destfolder+'/%s' % file.name, 'wb+') as dest:
            for chunk in file.chunks():
                dest.write(chunk)

我想对视图进行单元测试.我计划测试快乐路径和失败路径..即，request.FILES 没有关键文件"的情况，如果 request.FILES['file'] 有 None..

I would like to unit test the view.I am planning to test the happy path as well as the fail path..ie,the case where the request.FILES has no key 'file' , case where request.FILES['file'] has None..

如何设置快乐路径的post数据?谁能告诉我?

How do I set up the post data for the happy path?Can somebody tell me?

推荐答案

来自 Client.post:

提交文件是一种特殊情况.要发布文件，您只需要提供文件字段名称作为键，以及文件的文件句柄您希望作为值上传.例如:

Submitting files is a special case. To POST a file, you need only provide the file field name as a key, and a file handle to the file you wish to upload as a value. For example:

c = Client()
with open('wishlist.doc') as fp:
  c.post('/customers/wishes/', {'name': 'fred', 'attachment': fp})
